PIERCING AND eYELsTINe MACHINE.

SPECIFICATION forming part of Letters Patent No. 629,000, dated July 18,1899-.

Application filed November 17, 1898. Serial No. 696,706. (No model.)

the following is a full, clear, and exact description.

This invention relates to a machine for piercing cloth and other similarand suitable material and for iixing eyelets in the holes formed by thepiercers. The piercing and eyeleting is performed in one motion of theinachine, and one or any convenient number of holes may besimultaneously formed and eyeleted.

The accompanying drawings, to which I will hereinafter refer, illustratethe construction of the improved machine.

Figure l represents the complete machine in front elevation. Fig. 2shows it in side elevation. Fig. 3 is a back elevation of part of themachine. Fig. 4 illustrates a part of .the brush which is employed inthe eyeletbox to keep the eyelets agitated and to feed them into thechute or chutes. Fig. 5 is an enlarged View of a piercer and itsaccessories soon after it has commenced its stroke. Fig. 6 is a similarview of the same parts in different relative positions. Fig. 7 is afurther illustration of the same parts when the piercer is at the end ofits stroke and the eyelet is being riveted in place. Fig. 8 shows amodification. s Y

It will of course be understood that although the machine illustrated isrepresented witha multiplicity of piercers these improvements areequally applicable to a machine in which only one or any otherconvenient number of piercers are employed.

In its simplest form, then, the machine consists of a piercer whichmoves upward and pierces the cloth or similar material, then en- Y gagesitself with an eyelet, passes farther and the eyelets.

Referring to the drawings, A is a frame,

within which the slide B is capable of reciprocating vertically. It maybe operated in any desired manner, but preferably by the eccentrics C,secured to the main shaft D, or by means of cranks and connecting-rods.This slide is provided with a series of upwardly-projecting piercers E,each of which is formed with a thickened part or shoulder e, thefunction of which will be explained hereinafter. Above the piercers aseriesrof eyelet-chut-es Fis arranged, each chute opening into a `boxGr, which is mounted upon a shaft Hso as to be capable-of angularmotion. At the top of the machine is a fixed series of dies or anvils I,these dies corresponding in number with the piercers.

The material to be pierced and eyeleted is placed upon the table J withthe part to be pierced between the piercers and the overhangin g chuteends. The eyelets in the ends of thechutes are thus visible to theoperator. The machine is then set in motion. The piercers pass upwardand pierce the cloth or other material K, which is supported against thechutes F, the piercers passing through holes or openings formed in thechutes or between adjacent chutes or between proj eetions or hornsformed on the chutes. Inany case the chutes are so formed that each ofthem presents an eyelet L to the point of a piercer, the eyelets beingheld with their flanged parts uppermost. The piercers after perforatingthe cloth enter the eyelets, as shown in Fig. 5. The ends of the chutesare now withdrawn and the piercers are free to continue their upwardmotion, carrying with them the cloth K Fig. 6 illustrates a piercer whenthis stage has been reached. The point of the piercer now enters anaxial hole formed in its opposing die or anvil I, and the furthermovement of the piercer forces the eyelet into 'the cloth and clenchesit, the clenching being performed between the face of the die I and theshoulder c of the piercer E. This is shown in Fig. 7. The piercers arenow withdrawn and are freed from the cloth, the latter being held ordrawn off by the table J. The eyelet-chutes are now returned.

The chutes are preferably operated and withdrawn by the link N, Figs. 2and 3. The lower end of the link is pivoted to the slide B, and itsupper end engages by a slot n with a pin, stud, or shaft O, which isconnected with the chutes, they in turn being connected to theeyelet-box Gr, which, as before explained, is capable of angularmovement around the shaft II.

IVith the various parts in the positions shown in Fig. 2 it will be seenthat the first part of the upward movement of the slide B communicatesno motion to the chutes. As soon, however, as the piercers have engagedwith their eyelets the bottom of the slot n has come into contact withthe stud O, so that continued motion of the link withdraws the ends ofthe chute in the direction of the arrow. Upon the return motion of theslide the chutes are not returned until the upper end of the slotreaches the stud O and draws them back to their former position. takeplace until the piercers are low enough to permit of the motion.

In order to insure that the chutes remain in their withdrawn positionuntil it is time for them to return, a frictional device or brake may beemployed. This may consist of an arm Q, one end of which is looselyconnected to the stud O, while the other end is capable of passing underthe spring-controlled clamp The friction between the clamp and the armholds the chutes in their withdrawn position until the link N becomesoperative.

An improved device for insuring the constant agitation of the eyelets inthe box G whether the machine is working or not is represented in Figs.1, 2, 3, and 4. This device also permits of the agitation beingperformed byhand. l`vlountedlengthwisewithinthebox and capable ofreciprocating or sliding therein is a rod or shaft R. This rod carrieswire or other brushes r. (See Fig. 4:.) Pivoted upon the side of the boxis a crank-lever S, provided with a handle s and pulled constantly inone direction by the spring S. The lever is connected to the sliding rodR by the connecting-rod R. Upon the end of the box and in a plane atright angles to the plane of the lever S is mounted a second crank-leverT, one of the limbs of which comes below one of the limbs of the leverS, as clearly shown in Figs. 2 and 3. The other limb of the lever T isconnected by a rod t to a short crank or eccentric upon theconstantly-running rstmotion shaft U. As long as this shaft is running,therefore, the levers S and T have angular motion imparted to them, andthe rod This does not R and the brushes r' are reciprocated. Should itbe desired to agitato the eyelets when the shaft U is at rest, it caneasily be effected by moving the lever S by the handle s.

The chutes may be of the usual construction and arrangement, with theexception .that their ends are formed to support the cloth duringpiercing; but it is preferred to form them with their channelsapproximately resembling a letter V in section instead of making thechannels conform to the shape of the eyelet, as is usual. By theimproved section shown in Fig. 5 the sides of the channel in the chuteare straight and have no recesses which may become choked up. The riskof the eyelets becoming jammed is thus much reduced and the chute may bemore easily cleaned when necessary.

Fig. 8 illustrates'in section a modiied form of chute in which thechannel, although V- shaped, is formed with small flat ledges or flangesY at its narrowest part to support the neck or narrow part of theeyelet.

The first-motion shaft U drives the main I shaft D by means of thepinion V and the wheel V', and the main shaft is thrown into gear by asuitable clutch WV, which is operated by a treadle X in the manner usualin eyeleting-machines.
